Limiting Factors

Lion and Warthog- African lions are known for hunting warthogs because they are sometimes easy to catch. If a drought were to occur in the savanna, the warthogs might die out leaving it for the lions to find something else to prey on.

Herbivore

Carnivores

Omnivore

Scavengers

Food Chains and Food Webs

Food chains are just the flow of one organism to the next. Food webs are multiple food chains interacting.

If you took away the harvester ant, then the population of the pangolin would eventually die out because that's what they mainly eat.

Trophic Levels and Energy Pyramids

The use of a pyramid shows how there is less and less energy as the trophic levels advance. Producers are at the bottom because they receive energy directly from the sun. Top predators are at the top be cause they receive the least amount of energy.

Photosynthesis

Chemical Equation- 6CO2+6H2O

Reactants for photosynthesis- carbon dioxide and water

Products of photosynthesis- oxygen and glucose

Photosynthesis takes place in chloroplasts

The energy transformation in photosynthesis is radiant energy to chemical energy

Tropisms

Tropism- when a plant grows toward or away from stimuli Ex: Phototropism(movement towards the sunlight), Geotropism(movement towards gravity), Hydrotropism(movement in response to water), Thigmotropism(movement in response to touch)

The Role of Decomposers

Decomposers are vital to the savanna because without them there would be a lot of dead plants and animals everywhere.

Decomposers in the savanna- Earthworms, Insects, Bacteria, Fungi

Adaptations

Adaptations are important because they help organisms survive in and adapt to their environment . For example, lions blend in with the tall grass making it easier to catch their prey.

Giraffes have long necks to reach the leaves out of the trees. Lions blend in with the grass to catch their prey.

If you put a lion in an arctic ecosystem, it would freeze because its coat of fur isn't very thick.

Natural Selection

Natural selection- when organisms adapt to their environment so that they can survive

In the savanna, there are giraffes with short necks and giraffes with long necks. If something were to happen that made all the low-lying shrubs to die out, the giraffes with short necks would not get enough food. After a few generations, all of the giraffes with short necks would no longer exist, they would all have long necks.
